In Situ Chemical Oxidation with Minimal Exothermic Reactivity and Compatibility with Underground Infrastructure

  • Promotes rapid and sustained in situ oxidation of a wide-range of organic contaminants
  • Provides a unique catalytic surface on which oxidants and contaminants react in a process known as “surface mediated oxidation”
  • Non-corrosive, with minimal heat and pressure – compatible with underground infrastructure, tanks, piping, etc.
  • Creates a significant, short-term oxygen footprint to quickly establish follow-on aerobic biodegradation conditions
  • Readily desorbs contaminants from soil surfaces allowing for more effective ISCO and/or mechanical removal/extraction
  • Longer-term ISCO reactivity on the order of 30 days post-injection
  • Easily applied with readily available equipment

9 Reasons to Consider In Situ Chemical Oxidation

A Two-Part System Producing Powerful Chemical Oxidation Reactions

RegenOx® in situ chemical oxidation (ISCO) directly oxidizes contaminants while its unique catalytic component generates a range of highly oxidizing free radicals that rapidly and effectively destroy a range of target contaminants including both petroleum hydrocarbons and chlorinated compounds. RegenOx is an injectable, two-part ISCO reagent that combines a solid sodium percarbonate based alkaline oxidant (Part A), with a liquid mixture of sodium silicates, silica gel and ferrous sulfate (Part B), resulting in a powerful contaminant destroying technology.

Once emplaced in the subsurface, RegenOx produces a cascade of highly-efficient chemical oxidation reactions via a number of mechanisms including:

  • Surface mediated oxidation
  • Direct oxidation
  • Free radical oxidation

These reactions destroy a range of contaminants and can be propagated in the presence of RegenOx for periods of up to 30 days on a single injection.

RegenOx produces minimal heat and pressure and is non-corrosive making it a relatively safe chemical oxidant that is compatible for use in direct contact with underground infrastructure such as utilities, tanks, piping communication lines, etc. As a result the material can be applied using a wide-range of standard field equipment (e.g. direct push injection rigs) or applied directly into excavations.

In addition to chemical destruction, RegenOx ISCO produces a significant, short-term oxygen footprint that is optimal for establishing aerobic conditions capable of supporting follow-on, aerobic biodegradation of petroleum hydrocarbons. Once aerobic conditions are in place, many remediation practitioners apply Oxygen Release Compound Advanced (ORC Advanced) with or after RegenOx to support long-term aerobic biodegradation. This “ISCO to bio” combined remedies approach can be highly effective at reducing a range of contaminant concentrations and associated costs.

Finally, RegenOx based-reactions produce mild, detergent-like effects that desorb or remove contaminants off of soil surfaces and transfer contaminants more readily into the dissolved-phase. This process of removing material from soil surfaces has also been proven to be highly effective at increasing the efficiency of established, groundwater pump and treat (P&T) systems that have gone asymptotic. This desorption effect has been optimized in a specialized version of RegenOx called PetroCleanze which is designed for use in enhancing and optimizing multi-phase extraction (MPE) activities and P&T systems during site remediation.
